if two libraries have classes that have the same class& package name for their internal use

Question

I have two jars that have the same package structure. And they have a class that have the same name. like..

lib1.jar
   - A.class
   - Same.class
lib2.jar
   - B.class
   - Same.class

Actually, I don't use Same.class but it is used by class A and B

Then, what happened?

If lib1.jar is loaded first, only Same.class in lib1.jar is used for both A.class and B.class?

or A & B will use different Same.class in their own jar?

@TimBiegeleisen , Yes, they have the same package structure, and I cannot change them. — user2037661, Jan 02 '20 at 02:52
Yes, you should never build your jars this way. The classloader will only load one class per fully-qualified name. — Dawood ibn Kareem, Jan 02 '20 at 02:53
If you ever make your code modular (Java 9+) then what you're describing will be impossible because split-packages are not allowed by the module system. — Slaw, Jan 02 '20 at 03:03

If there isn't any special Class loader , which loads different classes at run time, the class loaded first will be used in both the places. Please check this for more info.
